To test an economically reasonable method to reduce thermal stress, we performed an alternated intervention-control study on 2 groups of 8 male steel workers performing the same jobs, using 2 l of water at ambient temperature (23.5°C ± 1.4), poured on the head and hands. Each group participated for 2 d as control and 2 d as intervention during 4 consecutive summer days in Brazil, 5 h per shift ...

A 9 pm cutoff 256x256 hand-held quantum well infrared photodetector (QWIP) camera has been demonstrated. Excellent imagery, with a noise equivalent differential temperature (NEAT) of 26 mK has been achieved. In this paper, we discuss the performance of this portable long-wavelength infrared camera in quantum efficiency, NEAT, minimum resolvable temperature difference (MRTD), uniformity, etc. an...

analyses and thermal infrared channels 4 and 5 NOAA- AVHRR images. This research was carried out in Lut Desert located in center of sub-tropical divergence dominant in' Iranian plateau. The physical and thermal properties of the various desert surfaces have been determined using correlation relationships between the desert variables including: dark sand, normal sand, marl, saline soil, soil dep...

Due to the impact of global warming and extreme weather events, outdoor human thermal comfort conditions become tougher harder mitigate, especially for pedestrian movement exercises. In order better understand environment comfort, sports, 2021 National Intercollegiate Athletic Games held in Tainan, southern Taiwan, May was selected as research target. Both on-site, real-time environmental monit...

The 2020 summer Olympic and Paralympic Games in Tokyo were postponed to July–September 2021 due the coronavirus disease 2019 (COVID-19) pandemic. While COVID-19 has emerged as a monumental health threat for mass gathering events, heat illness must be acknowledged potentially large maintaining services. We examined number of admissions rule emergency medical care, Tokyo, from March September 202...

Underground mines are a special type of environment which requires significant attention since they directly relate to miners‟ productivity, health and safety. With coal or ore exploitation into deep underground mine environments, high temperature and humidity creates risks because of large amounts of heat generated from geothermal heat, mining machines, groundwater and mine water. There have b...

More than 40 heat indices are being used across the world to quantify outdoor thermal comfort. The selection of an Outdoor Heat Stress Index (OHSI) depends on several parameters, including clothing, age, awareness, local environment, food consumption, human activities, and resources. This study investigates various indicators stress, (i) OHSIs officially stress worldwide, (ii) estimation method...
